Hello everyone and thank you for providing us with this wonderful framework.
I would like to point out that the puitreetable works in a particular way.
In fact, while the display of the "first levels is normal", the display of the children is inverse. So if I take as nodes:

A
--1
--2
--3
B
C
--5
--6
D

the display will be

A
--3
--2
--1
B
C
--6
--5
D

I think it's a bit of a counterintuitive thing even if I have seen that it is described in this way in the manual.
I just wanted to point out this particularity and know if it's an issue or a feature
Thanks anyway
Maurizio
